Specification of Letters Patent.

-Patented Oct. 2, 191?.

Application filed April 13, 1917. Serial No. 161,860.

a citizen of the United "States, residing at Puyallup, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Operating Structures for Closures; and I do hereby declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a mechanism particularly. designed for closing gates, doors or the like, which mechanism is operated through the pivotal movements of trip or operating levers so that in case it is employed in connection with gates, .the gates may be opened by the striking'and locking of a lever by a vehicle so as to eliminate the necessity of the person alighting from the vehicle for opening the gates. Or, the de vice may be applied for opening doors so that the doors may be opened by the foot of the operator pressing uponcthe pivoted levers, and closed in the same manner.

lVith the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated inthe accompanying drawings and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a View illustrating in side elevation the closure operating mechanism and showing the gates or closures open in dotted lines; I

Fig. 2 is a view looking at the opposite side of the mechanism from that shown in Fig. 1;

Fig. 3 is an endview of the mechanism;

F ig. 4 is a section through the mechanism, taken on the line 44 of Fig. 1.

Referring more particularly to the drawings, 1 designates the platform which supports the closures when in a closing position. The platform 1 is positioned over a pit and is supported by suitable standards 2. If it is so desired, the entire mechanism may be inclosed within a housing indicated at 8. t

The closures, which may be gates or doors, which are indlcated by the numerals 4 and 5 have depending arms 6 formed upon their lower outer corners which arms project downwardly through the platform 1 and are pivotally connected as shown at 7 to the outermost supporting standards 2 so as to allow the closures 4 and 5 to swing in a vertical plane upon the pivot 7 for moving them into an open or closed position. A

pair of guiding cleats 8 are carried by the platform 1 and they are positioned-forholding the-lower free edges of the gates or closures 4 and 5, against accidental horizontal movement. I

A shaft 10 is rockably supported by the center standards 2 and it has a drum 11 mounted thereon which drum is preferably provided with a concaved periphery. The

shaft 10 is rectangular shaped in cross section so that it will rotate in unison. with the rotation of the drum 11. A cable 12 is attached to the drum 11 for winding thereon and it passes over a sheave pulley 13 which is suspended from the under surface of the platform 1, downwardly from the sheave pulley 13 to and about a sheave 14 which extends upwardly from the base 15. The rope or cable 12 passes from the sheave pulley 14 to beneath an idler, pulley 16 which is also supported by the base 15 and it is connected as shown at 17 to the lower end of a trip lever 18. The trip lever 18 is pivotally supported intermediate its ends as shown at 19 and its upper end 20 projects above the casing 23.

The upper end 20is positioned in the path of a vehicle or'anoperators foot, sothat when the lever is moved in the direction indicated by the arrow A in Fig. 3 of'the drawings, the cable 12 will be pulled outwardly in the direction indicated by" the arrow B in Fig. 3 of the drawings. The outward pulling of the cable 12 will rotate the drum l1 and consequently the shaft 10 for swinging the closure members 4 and 5 upon their pivot 7, into an open position as indicated in dotted lines in Fig. 1 of the drawings. The closures 4 and 5 are swung into an open position upon pivotal movement of the lever 18 by cables 21 and 22. The cable 21 has .eye' 27 has a second cable 31 connected 4O 3 of the drawings and this rotates the drum one end connected to an eye 23, which eye is in turn carried by the upper end of a rod 24 which extends diametrically through the shaft 10 at an obtuse angle to the vertical as clearly shown in Fig. 2 of the draWingsJand it passes over sheave' pulley' 25,-and is connected as shown at- -26to an eye 27 carried by the lower end of the arm 6 which projects downwardly from'the lower outer corner of the closure member 4:. The cable the scope of what is claimed.

22is connected to'an eye28 carried by the lower end of the rod 2 L and it passes about pulleys 29 and is connected to an eye 30 carried by thelower end of the arm 6 which is formed'upon the closure member 5. The

thereto, which passes over a sheave pulley 32 and is connected to the eye 28. A cable 33 is connected to the eye 23, passes over a pulley 34: and is connected to the eye 30. s

The drum 11 hasa second cable 36 connected thereto which passes about a pulley 37.1and a second pulley 38. The cable 36 is connectedto a lever 39 intermediate its ends as shown at 4:0. The lever 39 has its lower end pivotally connected as shown at41 to a suitable brace 42 and itsupper end 43 pro- .jects above the top of the casing 3 and the platform 1' as clearly shown in Fig. 4 of the drawings, so that when the lever 39 is moved outwardly into the position indicated in Fig. 4 of the drawings, the closure members at and 5 will be swung into a closed position, at which time the lever 18 will be. moved into an operative position, through, the an rang'ement and connections of the various ropes .or cables.

When avehicle strikes the upper end of the lever-20, it pulls the cable 12 in the direction indicated by the arrow B in Fig.

11: forwinding a1 limited amount of the cable 36 thereon. The rotation of the drum 11' as'above mentioned will rotatethe shaft .10 and consequently move the rod at so that it will pull upon'the cables 21 and '33 for i rocking the closures l and 5 upon their piv- 'ots7 and moving them into open position. The closures remain 1n an open position untllthe lever39 1s moved into the position unwinds the cable 36 from the drum 11,

winds theca'ble 12 thereon and rotates the shaft 10in a" direction oppositely to, which it is rotated by the pivotal movement ofthe V lever 18, causing the rod 24L to move in a directionfor pulling upon the cables '22 and 31 which moves the closures 4 and 5 into their normal closed positions.

7 From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved operating structure for closures will bereadily apparent to those skilled in the art to which upon pivotal movement of the trip levers.
